@sv 92 ,3 f Q i Y 3 m .A ,rl m. Q uw clamps the upper' flange 25 of the supporting sleeve 23 to the upper end of the main casing as shown. The upper end of the gland nut 3l is reduced in section similar to lAmong the advantages not mentioned may be noted that accruing when it is desired to change from a self-closing to a compression cock, as the connection of the shank of the valve casing with the supply pipe is diiiicult to make or is diiiicult or impracticable to reach. In thatcase the self-closing operating means is reY moved and the compression cock operating means substituted, Whereupon'the self-closing cock becomes a. compression coclnand operates with all the ett'iciency of the standard compression cock.

A prime advantage derived from i'ny invention is that it meets with the demand of hotel and public resort keepersyfor an` interchangeable seit-closing and compression cock. By using my invention, a l hotel plumber can change a self-closing cock to a compression cock in an incredibly short time and since some people want a steady tloiv ot' Water, while others Want a limited flow, the varied desire ot patrons is easily met.

While I have described the best form ot my invention known to me, it should be obvious that my invention may be given several forms without departing in anywise from its generic spirit, and all o f these forms I therefore desire to cover in the annexed claims. f

What I claim is:

1. In combination with a valve casing constructed to receive the associate parts oi a seit-closing cock, means for converting the leelt closing cock to a manually operated cock, said means comprising a sleeve for insertion in the valve casing, a gland nut carried on the casing for binding the sleeve therein and being reduced and dished out at its upper end, compression operating means in the sleeve having a stein projecting' up through the gland nut, and a handle on the upper end of the stem provided with a bonnet overlapping the upper reduced end of the gland nut to house the stem at all adjustments of the manually operated valve.

J2. In combination with a valve casing constructed to receive the associate parts of a self-closing-cock, convertible means for the cock to adapt itforimanual closing, said means comprising a sleeve for insertion in the -valve casing, compression operating, means carried by the sleeve, a gland nut earlried by thecasing for lbinding the sleeve therein, and a handleassociated With the operating means and having a bonnet inclosing the upper end oi the gland nut. whereby to house said operating means.

3. In combination with a valve casingh aving a stem therein provided with, a valve, a handle on the valve stem having an in'- clined-trackvvay in its underside, a detachable gland nut on the casing supporting said stem and provided with an inclined track- Way on its upper end, rollers interposed between the Vtrackvvays, and a spring normally urging the trackways together Whereby to close said valve automatically, means for converting said automatically closing cock to a manually' operable cock, said 85 means comprising a threaded stem provided with a valve, a threaded sleeve ior inser-` tion in the casing and engaging in threaded relation with said stem, a gland nut carried on the casing adapted to hold said sleeve in the casing, and a handle on the stein for turning' the same and being provided with a bonnet adapted to close lthe upper end of the gland nut.

In testimony whereof I have hereunto set iny hand in presence of tivo subscribing Witnesses.
